2020-07-31crypto: ccp - use generic power managementVaibhav Gupta
Drivers using legacy power management .suspen()/.resume() callbacks have to manage PCI states and device's PM states themselves. They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions as through the generic framework, PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

It is known that Mediatek owns two thermal systems, which only differ in the way of reading calibration data and converting temperature.

2020-07-31drm/nouveau: Accept 'legacy' format modifiersJames Jones
Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK() family of modifiers to handle broken userspace Xorg modesetting and Mesa drivers. Existing Mesa drivers are still aware of only these older format modifiers which do not differentiate between different variations of the block linear layout. When the format modifier support flag was flipped in the nouveau kernel driver, the X.org modesetting driver began attempting to use its format modifier-enabled framebuffer path. Because the set of format modifiers advertised by the kernel prior to this change do not intersect with the set of format modifiers advertised by Mesa, allocating GBM buffers using format modifiers fails and the modesetting driver falls back to non-modifier allocation. However, it still later queries the modifier of the GBM buffer when creating its DRM-KMS framebuffer object, receives the old-format modifier from Mesa, and attempts to create a framebuffer with it. Since the kernel is still not aware of these formats, this fails. Userspace should not be attempting to query format modifiers of GBM buffers allocated with a non- format-modifier-aware allocation path, but to avoid breaking existing userspace behavior, this change accepts the old-style format modifiers when creating framebuffers and applying them to planes by translating them to the equivalent new-style modifier. To accomplish this, some layout parameters must be assumed to match properties of the device targeted by the relevant ioctls. To avoid perpetuating misuse of the old-style modifiers, this change does not advertise support for them. Doing so would imply compatibility between devices with incompatible memory layouts. Tested with Xorg 1.20 modesetting driver, weston@c46c70dac84a4b3030cd05b380f9f410536690fc, gnome & KDE wayland desktops from Ubuntu 18.04, and sway 1.5 Reported-by: Kirill A.

2020-07-30net/mlx5e: fix bpf_prog reference count leaks in mlx5e_alloc_rqXin Xiong
The function invokes bpf_prog_inc(), which increases the reference count of a bpf_prog object "rq->xdp_prog" if the object isn't NULL. The refcount leak issues take place in two error handling paths. When either mlx5_wq_ll_create() or mlx5_wq_cyc_create() fails, the function simply returns the error code and forgets to drop the reference count increased earlier, causing a reference count leak of "rq->xdp_prog". Fix this issue by jumping to the error handling path err_rq_wq_destroy while either function fails.

2020-07-30net/mlx5e: E-Switch, Add misc bit when misc fields changed for mirroringJianbo Liu
The modified flow_context fields in FTE must be indicated in modify_enable bitmask. Previously, the misc bit in modify_enable is always set as source vport must be set for each rule. So, when parsing vxlan/gre/geneve/qinq rules, this bit is not set because those are all from the same misc fileds that source vport fields are located at, and we don't need to set the indicator twice. After adding per vport tables for mirroring, misc bit is not set, then firmware syndrome happens. To fix it, set the bit wherever misc fileds are changed. This also makes it unnecessary to check misc fields and set the misc bit accordingly in metadata matching, so here remove it. Besides, flow_source must be specified for uplink because firmware will check it and some actions are only allowed for packets received from uplink.

Fixes: 87ab207981ec ("net: nixge: Separate ctrl and dma resources") Fixes: abcd3d6fc640 ("net: nixge: Fix error path for obtaining mac address") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Lu Wei <luwei32@huawei.com> Signed-off-by: David S.

2020-07-30ptp: ptp_clockmatrix: update to support 4.8.7 firmwareMin Li
With 4.8.7 firmware, adjtime can change delta instead of absolute time, which greately increases snap accuracy. PPS alignment doesn't have to be set for every single TOD change. Other minor changes includes: adding more debug logs, increasing snap accuracy for pre 4.8.7 firmware and supporting new tcs2bin format.

2020-07-30drm/msm/dpu: ensure device suspend happens during PM sleepKalyan Thota
"The PM core always increments the runtime usage counter before calling the ->suspend() callback and decrements it after calling the ->resume() callback" DPU and DSI are managed as runtime devices. When suspend is triggered, PM core adds a refcount on all the devices and calls device suspend, since usage count is already incremented, runtime suspend was not getting called and it kept the clocks on which resulted in target not entering into XO shutdown. Add changes to force suspend on runtime devices during pm sleep. Changes in v1: - Remove unnecessary checks in the function _dpu_kms_disable_dpu (Rob Clark). Changes in v2: - Avoid using suspend_late to reset the usagecount as suspend_late might not be called during suspend call failures (Doug). Changes in v3: - Use force suspend instead of managing device usage_count via runtime put and get API's to trigger callbacks (Doug). Changes in v4: - Check the return values of pm_runtime_force_suspend and pm_runtime_force_resume API's and pass appropriately (Doug). Changes in v5: - With v4 patch, test cycle has uncovered issues in device resume. On bubs: cmd tx failures were seen as SW is sending panel off commands when the dsi resources are turned off. Upon suspend, DRM driver will issue a NULL composition to the dpu, followed by turning off all the HW blocks. v5 changes will serialize the NULL commit and resource unwinding by handling them under PM prepare and PM complete phases there by ensuring that clks are on when panel off commands are being processed. Changes in v6: - Use drm_mode_config_helper_suspend/resume() instead of legacy API drm_atomic_helper_suspend/resume() (Doug). Trigger runtime callbacks from the suspend/resume call to turn off the resources. Changes in v7: - Add "__maybe_unused" to the functions to avoid compilation failures. Cleanup unnecessary configs (Doug). Signed-off-by: Kalyan Thota <kalyan_t@codeaurora.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Rob Clark <robdclark@chromium.org>
2020-07-30drm/msm: handle for EPROBE_DEFER for of_icc_getJonathan Marek
Check for errors instead of silently not using icc if the msm driver probes before the interconnect driver. Allow ENODATA for ocmem path, as it is optional and this error is returned when "gfx-mem" path is provided but not "ocmem". Because msm_gpu_cleanup assumes msm_gpu_init has been called, the icc path init needs to be after msm_gpu_init for the error path to work.

2020-07-30drm/msm: reset devfreq freq_table/max_state before devfreq_add_deviceJonathan Marek
These never get set back to 0 when probing fails, so an attempt to probe again results in broken behavior. Fix the problem by setting thse to zero before they are used. Signed-off-by: Jonathan Marek <jonathan@marek.ca> Signed-off-by: Rob Clark <robdclark@chromium.org>
